Parisians were likely to spot more rats than usual in coming days as the Seine continued to rise Wednesday after heavy rains, while part of the Louvre was closed as artworks were moved to higher ground.
Much of France has been lashed by downpours throughout January, inundating many homes and shops with muddy water and halting trains on a busy commuter line that runs through Paris.
The Seine is expected to reach 6.2 metres (20.3 feet) on Saturday, a peak last reached in 2016 when floods sent riverside museums scrambling to move artworks from their basements, which was the highest level since 1982.
Paris's rat problem has gotten much more visible as their dens are swamped with water, forcing them to seek drier shelters.
